Magnesium deficiency in plants: An urgent problem

Crop Journal, 2016
Although magnesium (Mg) is one of the most important nutrients, involved in many enzyme activities and the structural stabilization of tissues, its importance as a macronutrient ion has been overlooked in recent decades by botanists and agriculturists ...

Physiological Essence of Magnesium in Plants and Its Widespread Deficiency in the Farming System of China [PDF]

Frontiers in Plant Science, 2022
Magnesium (Mg) is an essential nutrient for a wide array of fundamental physiological and biochemical processes in plants. It largely involves chlorophyll synthesis, production, transportation, and utilization of photoassimilates, enzyme activation, and ...

Two transporters mobilize magnesium from vacuolar stores to enable plant acclimation to magnesium deficiency [PDF]

Plant Physiology, 2022
Abstract Magnesium (Mg) is an essential metal for chlorophyll biosynthesis and other metabolic processes in plant cells. Mg is largely stored in the vacuole of various cell types and remobilized to meet cytoplasmic demand. However, the transport proteins responsible for mobilizing vacuolar Mg2+ remain unknown.

Magnesium isotope fractionation reflects plant response to magnesium deficiency in magnesium uptake and allocation: a greenhouse study with wheat [PDF]

Plant and Soil, 2020
Abstract Aims Magnesium (Mg) deficiency is detrimental to plant growth. However, how plants respond to Mg deficiency via regulation of Mg uptake and allocation is yet not fully understood. In this study, we tested whether Mg isotope compositions (δ26Mg) associated with Mg mass balance of the plants could be used as an indicator to trace Mg uptake and ...

DIFFERENCES IN GROWTH LIMITATION OF CERTAIN PLANTS BY MAGNESIUM AND MINOR ELEMENT DEFICIENCIES [PDF]

Plant Physiology, 1942
A number of commonly grown plants were chosen for an experiment to determine if certain Alabama soils were deficient in magnesium and the so-called "minor'' elements. The different plants varied so much in growth when the soils were deficient in these elements that a description of the differences appears to be valuable from both the physiologic and ...

Critical Issues in the Study of Magnesium Transport Systems and Magnesium Deficiency Symptoms in Plants [PDF]

International Journal of Molecular Sciences, 2015
Magnesium (Mg) is the second most abundant cation in living cells. Over 300 enzymes are known to be Mg-dependent, and changes in the Mg concentration significantly affects the membrane potential. As Mg becomes deficient, starch accumulation and chlorosis, bridged by the generation of reactive oxygen species, are commonly found in Mg-deficient young ...

Magnesium deficiency decreases biomass water-use efficiency and increases leaf water-use efficiency and oxidative stress in barley plants [PDF]

Plant and Soil, 2016
In water-scarce agro-environments a clear understanding of how plant nutrients like magnesium (Mg) affect plant traits related to water-use efficiency (WUE) is of great importance. Magnesium plays a crucial role in photosynthesis and is thus a major determinant of biomass formation.

Genome-wide identification of MGT gene family in soybean (Glycine max) and their expression analyses under magnesium stress conditions [PDF]

BMC Plant Biology
Background Magnesium (Mg) is essential for plant growth and development and plays critical roles in physiological and biochemical processes. Mg deficiency adversely affects growth of plants by limiting shoot and root development, disturbing the structure

Symptoms and growth components in feijoa (Acca sellowiana [O. Berg] Burret) plants in response to calcium, magnesium and boron deficiencies

Revista Colombiana de Ciencias Hortícolas, 2023
Nutrient deficiency symptoms are widely used to determine the nutrient demands of a crop and to clarify nutritional disorders, especially when they are nutrient specific. Until now, a calcium (Ca), magnesium (Mg) and boron (B) deficiency experiment has not been carried out on feijoa, and diagnostic symptoms have not been described.

Influence of Magnesium Deficiency on Induction of Activity of Antioxidative Enzymes and Increased Tolerance to Active Oxygen-Generating Herbicides in Cucumber and Kidney Bean Plants.

Journal of Weed Science and Technology, 1998
The influence of a deficient (7μM) or sufficient (1000μM) supply of magnesium (Mg2+) on the content of Mg2+, chlorophyll and protein, and the activity of superoxide dismutase (SOD), ascorbate peroxidase (AP) and glutathione reductase (GR) were studied in cucumber (Cucumis sativus L.) and kidney bean (Phaseolus vulgaris L.) plants over an 11-day period.
